When I arrive at the home page, there is no sign in option. There is an option to register, but not to sign in. I have to attempt to reply to a thread to get the sign in page. What happened to the sign in option?

I am using Firefox and it automatically deletes all cookies every time I close the browser, so the remember me option is useless. I was able to sign in the first few time I came back to this site. Any suggestions?
